Changan Kuayue Xingta Summer Driving Safety Guide: High-Temperature Hazards and Protection Tips

Changan Kuayue Xingta Releases Essential Summer Driving Safety Guide for Light Trucks

As temperatures soar in summer, road surface temperatures keep rising, significantly increasing the operating load of freight vehicles. Drivers who overlook heat dissipation, high-temperature brake wear, or overloading face sharply higher risks. Below are the key high-temperature hazards and protection tips for fuel-powered and battery-electric light trucks.

Hazards and Protection Tips for Fuel-Powered Light Trucks

Risk of Tire Blowouts in High Heat

Road surface temperatures can reach up to 70°C in summer. Rear tires under heavy loads dissipate heat slowly and accumulate heat rapidly. Low tire pressure and overloading intensify tire deformation and heat buildup, greatly raising the risk of high-speed blowouts and rollovers.

Protection Tips

• Adjust tire pressure to the manufacturer's maximum rated pressure for full loads when tires are cold. Never release air or lower pressure on hot tires.
• Clear embedded foreign objects from treads before departure and inspect for sidewall bulges and cracks. Steering-wheel tread depth shall be no less than 3.2 mm, and other wheels no less than 1.6 mm; replace tires early once depth drops to 2.0–2.4 mm under heavy summer loads.
• Stop every two hours on long trips and let tires cool naturally in the shade. Never rapidly cool hot tires with cold water or wet towels.

Risk of Brake Fade Under High Temperatures

Frequent braking on long downhill stretches in high heat may cause vapor lock in hydraulic brake fluid, resulting in spongy brake pedals and extended braking distances.

Protection Tips

• Inspect brake pipelines monthly to eliminate leakage and bulging risks.
• Replace brake fluid every 2 years or 50,000 km; replace immediately if it turns turbid or deteriorated.
• Shift to low gear in advance for heavy-load downhill travel and use engine braking to reduce frequent braking.

Risk of Engine Overheating

When diesel light trucks carry cargo uphill or travel at high speed, engines operate under heavy load. Dust and oil buildup on heat-dissipation grilles may trigger overheating, while overloading can cause coolant boiling, cylinder scuffing, blown cylinder gaskets and permanent engine damage.

Protection Tips

• Replace coolant every 2 years or 40,000 km; check fan-belt tension monthly and keep coolant between MIN and MAX marks before departure.
• Avoid prolonged high-RPM climbing under heavy loads; reduce driving time during midday heat and stop periodically for heat dissipation.
• Pull over immediately and idle the engine if the coolant warning light activates. Do not switch off the engine or open the radiator cap when hot.

Hazards and Protection Tips for Battery-Electric Light Trucks

Risk of Battery Thermal Degradation

High-temperature fast charging, low state of charge, and high-power discharge during uphill driving widen cell temperature differences and accelerate thermal degradation, possibly triggering power limitation or a mid-route stall. Overloading sustains high battery output and speeds up cell aging.

Protection Tips

• Recharge when the charge level drops to 20%; avoid extremely low battery power and midday outdoor fast charging.
• Maintain steady speed when climbing and reduce hard acceleration to avoid sustained high-power battery output.
• Regularly inspect the battery pack for dents and water seepage, and check chassis high-voltage wiring for aging-related short-circuit risks.

Risk of Dual Brake Fade

Frequent braking during cargo transport easily causes brake disc overheating and fade on electric light trucks, while overloading further increases brake wear and lengthens braking distances.

Protection Tips

• Predict road conditions to avoid frequent hard braking, and control speed with mechanical brakes.
• Stop periodically on long hot-weather trips to check hub temperatures and prevent mechanical brake fade.
• Strictly adhere to rated load capacity and reject overloading to reduce brake-system strain from the source.

Key Safety Checklist at a Glance

Changan Kuayue Xingta: Purpose-Built for Heavy-Load High-Temperature Operation

Performing daily inspections and proper loading in hot weather can effectively prevent summer vehicle malfunctions. Changan Kuayue Xingta has carried out targeted optimizations for heavy-load high-temperature conditions:

• Fuel version: reinforced heavy-duty tires with high load capacity, excellent heat resistance and wear resistance.
• EV version: frame-embedded liquid-cooled battery pack paired with 250 mm high ground clearance, lessening road-surface thermal radiation, stabilizing battery temperature and mitigating thermal degradation under heavy loads.

Drivers should keep these safety tips in mind, observe rated load limits, conduct regular maintenance, and safely cope with the peak summer freight season.
